   My VTS stutters at high revs, above 4K but more frequently above 5K everything below is fine, pulls well up until the stutters and idles fine. Doesn't seem to do it when cold, or just been restarted.
   
   Coil pack and spark plugs are ok, just put some injector cleaner in to see if that helps. Next up are the injectors and if there ok im assuming the only thing left is a sticky valve?
   
   Thoughts?

   Could de down to fueling as under more throttle the more fuel u need could be blocked fuel filter maybe? Surely If it was a sticky valve I would notice it more under load say in 5th doing 30mph ??
